Evolution is no more obsolete than the life it tries to explain. In fact evolution, of all the scientific theories, has the most evidence to back it up. Since Darwin’s time there have been many scientific breakthroughs. Advancements in biology, chemistry and physics have all contributed their share to the evidence supporting the Theory of Evolution. The discovery of DNA and gene mapping technology also point to evolution as the process of change in living organisms. As more evidence is gathered the theory only becomes stronger and more complete.
Science demands facts, not assumptions or leaps of faith. Science also demands experiments that are repeatable and can be measured in some way. Without these basic requirements bias and personal beliefs can taint the evidence. There have been numerous theories, since the age of science, that had to be discarded after new evidence was discovered to disproved them. Some of these old theories were stubbornly fought for, but in the end the facts prevailed. Without these scientific methods who knows what we would believe in?
The goal of science is truth. Therefore only those things that can be measured can we know for sure. And only those things we can know for sure fall into the realm of science. Evolution therefore is not a belief system, it is a scientific theory. Unlike beliefs a scientific theory has to be modified or scrapped when new undisputable evidence warrants it.
Evolution has been studied, tested and attacked for well over a century and has remained relatively unchanged since Darwin first proposed it. If anything it has been made more complete over the years. What else could explain the fossil record, and the dinosaurs? What other reasonable explanation, based on the evidence, could there be for Neanderthal Man? How do you explain the mammoth? These questions, among many others, have been answered best by Charles Darwin in the Theory of Evolution.
Of course there will always be those that have their own theory of the origins of species, and may even have evidence to back it up. These challenges to established scientific thought are the driving force behind science itself. And it is by this constant challenging of the evidence that determines its strength. The latest challenge to the Theory of Evolution occurred not long ago. The theory that challenged it was called Intelligent Design. After all the evidence was presented, and all the arguments heard, the Theory of Evolution was judged to be stronger.
Everything changes. We see it everywhere we go. Trees fall down. Rocks crumble. Mountains erode. Glaciers advance and retreat. Species go extinct. And species evolve. Evolution is just as important now as it was the day it was written. And it will still be important in the future. It will always have its critics. And it will probably face many challenges, but it will never be outdated.
